Arm shield



Patented June 2, 1931 ERNEST S. LYDEN, OF DULUTH, MINNESOTA ARM SHIELD Application filed August 14, 1930. Serial No. 475,191.

This invention relates to arm shields to be used by an operator in the washing of automobiles, windows, or the like, and is designed particularly as a means for the prevention of water running down onto the arm or clothes of the operator.

The principal object is to produce a more eflicient and practical device of this character than heretofore known.

Other objects and advantages of the invention will appear in the further description thereof.

Referring now to the accompanying drawings, forming part of this application, and wherein like reference characters inclicate like parts:

Figure 1 is a central transverse sectional view through one of the improved shields; and

Figure 2 is a plan view of an entire shield as it appears from the convex face thereof.

The device is preferably formed of a dished-like piece of rubber 1, circular in form, and of substantially uniform thickness throughout except as respects the margin of the axial hole 2 therethrough, and

which marginal portion of the hole is formed with an enlarged annular bead 3 extending preferably upwardly Within the concaved side of the disc.

This hole 2 as is obvious is for the convenient slipping of the shield over the operators arm as is common in such devices, and the inner circumferential face of the bead 3 is provided with the annular groove i for the purpose of not only increasing the resiliency of the bead, but to increase its adherence to the arm by suction like effect.

From the bead 3 there extends radially a plurality of tapered reinforcing ribs 5 to reinforce and strengthen the disc, and adjacent the circumferential edge upon the opposite face is formed an extending annular flange-like drip bead 6, so that any water being discharged from the concaved surface of the shield may not readily follow inwardly upon the opposite surface when moved about during its use.

From the foregoing it is apparent that I have devised a simple, light and efficient ERNEST S. LYDEN.
